Bikability Rating System for Bellevue’s Roadways

This project utilized GIS data to create a bikability rating system for Bellevue, WA, based on various criteria such as facility type, slope, speed limits, bus routes, and proximity to bus stops. The analysis resulted in identifying the best biking routes while highlighting the challenges posed by interstates and state routes. The goal was to determine the most bike-friendly roads in Bellevue for enhanced transportation planning and safety.

  1. Determining the Bikability of Bellevue’s Transportation Network Stela Abed, Michael Cole, Yousef Al-Roumi, Tim Thomson, XinXin CEE 424 GIS for Civil Engineers December 8th 2010

  2. ObjectiveUse GIS data to form a bikability rating system for Bellevue’s roadway network. Bellevue, WA

  3. Data Collection • King County GIS Center • King County Bike Facilities • Metro Transit Bus Stops • Metro Transit Bus Routes • Transportation Network • City of Bellevue Standard Data • 2 Foot Topography • Street Network • Google • City of Bellevue aerial photograph

  4. Analysis - Criteria • Rated bike network based on: • Type of facility • Slope • Speed Limit • Along bus route • Proximity to bus stops • Along truck routes

  5. Model Equation Rating = 1.00 * [Bike Facility Type] + (0.85 * 40) * [Slope] + (0.75 / 10) * [Speed Limit] + 0.25 * [Overlaps Bus Route] + 0.25 * [Overlaps Truck Route] - 0.3 * [Within Bus Stop Buffer] • The smaller the rating the more bikeable the roadway.

  6. Results • Found best routes • Examined streets to verify index • All interstates & state routes - dangerous
